Definitions
- the invention relates to a method for manufacturing three-dimensional shaped pieces of a material having large pores, particularly honeycomb, after a block of this material has been trimmed by adjacently guided cuts of a predetermined cutting width along planes extending tangentially to the surface of the shaped piece to be manufactured, as well as to a cutting assembly for carrying out this method.
- the invention accomplishes this object by cutting into the block to the surface of the shaped piece before the tangential trimming or during the tangential trimming substantially along planes extending radially relative to the surface of the shaped piece, the kerfs extending longitudinally substantially parallel to each other and having a maximum distance from each other at the surface of the shaped piece, which corresponds to the width of the cut of the tangential cuts.
- These radial kerfs prepare the block for the operation of the tool for the tangential trimming since the paths defined by the kerfs make the trouble-free guidance of the tools along the respective tangential planes possible.
- the method may be rationally effectuated with a cutting assembly comprising a knife-equipped sonotrode or the like, whose knife has a shaft portion extending in the direction of vibration and a cutting portion attached thereto and extending transversely to the direction of vibration, the shaft portion and the cutting portion defining cutting edges so that the knife may be used simultaneously for cutting tangentially and radially. Therefore, the contours of shaped pieces can be cut out directly from the pre-fabricated block by suitably guiding the knife during cutting and the scrap is immediately cut off in ribbons during the cutting out of the shaped piece.
- the radial and tangential cuts could be made with separate knives, which permits sequential radial and tangential cuts.
- the scrap is detached from the remaining shaped piece in sections when the knife is advanced through the tangential cut before the radial cut is made so that the ribbon pieces may be more easily laterally split when the scrap is cut off and a better guidance of the knife may be obtained.
- Useful forms of knives may be obtained with a cutting portion consisting of an elongated knife platelet centrally disposed on the shaft portion, in which the knife platelet may have bent-up ends, or with a cutting portion consisting of a disc with a circumferentially extending cutting edge, in which the disc may be circular but also elliptical, kidney-shaped or the like.
- FIG. 1 shows a cutting assembly according to the invention for the manufacture of a shaped piece in side elevation, partly in section, and
- FIGS. 2 and 3 are perspective views of respective embodiments of a knife for the cutting assembly.
- shaped pieces F of honeycomb or the like are cut out of a pre-fabricated block B of material for the shaped piece, for which purpose an ultrasound cutting assembly 1 is provided with a sonotrode 2 equipped with a knife, which is mounted rotatably adjustably about rotary axes I, II extending perpendicularly to each other on a robot arm 3 (not further illustrated) which is controllable along several axes whereby any desired movements, including three-dimensional cuts, may be effected.
- shaped piece F is cut out of block B by adjacent cuts T of a predetermined width along planes extending tangentially to the surface of the shaped piece to be manufactured while, before the tangential cutting or during the tangential cutting, kerfs R are made substantially along planes extending radially towards the surface of the shaped piece, the kerfs extending approximately parallel to each other and at a maximum distance corresponding to the width of the tangential cuts in the area of these cuts from each other. This results in the remaining scrap being cut off bit by bit from block B in the form of ribbons A as shaped piece F is cut out.
- Radial kerfs R may be made with ultrasound cutting assembly 1 or a conventional incision knife, whereupon tangential cuts T are made by special knife 4.
- Knife 4 has a shaft portion 5 extending in the direction of vibration and a transversely extending cutting portion 6 at the end thereof so that the knife may be guided with its shaft portion 5 along radial kerfs R when cutting portion 6 is used for tangential cuts T.
- cutting portion 6 consists of an elongated knife platelet 6a centrally mounted on shaft portion 5a, ends 7 being bent upwards.
- a knife 4b may have a cutting portion consisting of disc 6b centrally mounted on shaft portion 5b to constitute a knife which may cut in all directions.
- shaft portions 5a, 5b may also have cutting edges 8 so that each knife 4a, 4b has a cutting edge extending transversely to the direction of vibration, i.e. longitudinally extending cutting edge 9a of knife platelet 6a or circularly extending cutting edge 9b of disc 6b, and a cutting edge 8 of shaft portion 5a or 5b extending in the direction of vibration to execute the desired cuts extending perpendicularly to each other. If the cutting edge of the shaft portion is recessed relative to the cutting edge of the cutting portion in the direction of cutting, as is shown in connection with knife 4b, more favorable splitting effects in cutting off the scrap and a more accurate guidance of the knife are obtained.
